A person is called a buyer when he buys a thing, be it a household thing, a vehicle, a land, a house or anything of his choice. But you should not be a mere buyer if you want to buy a thing that is supposed to serve the purpose for which it is bought. You have to be a ‘good buyer’ so that the thing that you buy lasts a long time. You have to be very choosy. For that yon ned to have in-depth knowledge about thing you want to buy. But you cannot have an expert knowledge in everything you buy in the world.
So what would you do? Rely on people who possesses expertise in that particular thing.
This approach is very much important especially when you want to buy an immovable property which involves lakhs and crores of rupees.
